BUNLE-CARRIER FOR HARVESTERS..

SPECIFICATION forming part of Letters Patent No. 383,009, dated May l51 1888.

Application tiled December 7,1887. Scrial No. 257,232. (No model.)

To @ZZ whom t may concern:

Beit known that I, DAVID H. Pnnwrrr, a citizen of the United States, residing at Perryville, in the county of Boyle and State of Kentucky, have invented a new and useful Improvement in Bundle-Carriers for Harvesters, of which the following is a specification.

My invention :relates to improvements in bundle-carriers for grain-binding harvesters;

and it consists in certain novel features, hereinafter first fully described, and then specifically pointed out in the claims.

In the annexed drawings, Figure 1 is a perspective view showing a portion of a harvester and myimproved carrier in connection therewith. Fig. 2 is a plan view showing the device as extended. Fig. 3 is a similar view showing it folded. Fig. 4L is a detail perspective view showing the mechanism by which the supporting bars are operated. Figs. 5 and 6 are detail views, in plan and side elevation, to show the form of the carrying-bars. Fig. 7 is a sectional view of the carrier, showing it in the position it assumes when supporting the bundles. Fig. 8 is a similar view showing the position assumed to dump the bundles, and Fig. 9 is a similar view showing the device folded to pass through narrow places.

Referring particularly to the drawings by letter, A. designates a portion of a harvesterframe, and B my improved bundle-carrier secured thereto. The said bundle carrier is composed of a frame, (Iwhich is U-shaped in plan view, (see Figs. 2 and 3,) having the ends of its side bars,'Z, secured to the harvesterframe and projecting therefrom in substantially a horizontal plane, and the inclined parallel arms D, which are securedto the harvester-frame and to the side bars of the U- shaped frame C, and have their front ends below and in the same vertical plane with the cross-bar of the said U-shaped frame. In the said front ends of the arms D, I journal a rockshaft, E, which is provided at one end with a crank-arm, F,which is connected to a treadle, G, arranged near the drivers seat, by suitable links and bellcrank levers. In the upper rear portion of this rock-shaft I form a longitudi- 50 nal recess, H, which extends nearly the entire length ofthe shaft, and is nearly equal in depth tothe diameter of the shaft. In the base of this recess I provide a longitudinal series of vertical openings, I, through which pass the inner vertical portions, J, of the carrying-bars 5 5 K. These carrying-bars project outward from the shaft E and the side of the harvester, as clearly shown in Fig. 1.

The upper extremities of the vertical portions .I of the carrying-bars are bent to one side to form the cranked portions L, the ends of which are pivoted to the cross-bar of the U- shaped frame C.

In operation the bundles pass from the binding mechanism of the harvester onto the carrier-bars, and when a sufficient number of bundles have been collected the driver depresses the treadle G, thereby operating the carrier, through the intermediate mechanism, to drop the bundles. When the bars are in the position shown in Figs. 2, 4, and 7, they will support the bundles, and are held in this position by reason of the upper edge of the longitudinal recess H bearing against the bars at the angles formed by the vertical portions Jand the crank-arms L, on theinner edge of the openings I against the lower part of the ver` tical portion J. Now, when the treadle is depressed, the crank-arm F is thrown outward, the bar E is rocked in the same direction, and consequently the upper edge of the said recess is moved away from the said vertical portions of the carrying-bars, as shown in Fig. 8. The weight of the bundles will consequently cause the outwardly-extending portions of the carrying bars or fingers to fall, as shown in Fig. 8, and as the said fingers or bars are not secured at any point, except where the crankarms L are pivoted to the frame C, they will at the same time swing around upon the pivotpoints of said crank-arms as a center to the position shown in Fig. 3, for the reason that the said crank-arms project rearward of the main portion of the bars. Vhile in this position, if the treadle be further depressed, the lower portion of the rock-shaft E will be turned upward, causing the openings I to assume the position shown in Fig. 9, the outer edge ofthe opening pushing against the outer sides of the vertical portions of the carryingbars, thereby throwing the carrying bars around to the position shown in said figure un der the frame C, and permitting the passage of the machine along roads and through gate- ICQ
